lA IL-COVER.

Application filed January 28, 1913.

My invention relates to improvements inpail covers, and more particularly to an improved fragile or destructible cover which is designed to seal the open ends of fire pails and the like, either containing-chemical or water, and whichmay be readily ruptured by a blow when it is desired to pour out the contents of the pail.

A further object is to provide a cover of this character which comprises a sheet of tin foil or other. similar water proof yet fragile material which is secured between rings, and one of said rings adapted to snugly fit within the open endof a pail.

A further object is to provide an improved construction of cover which enables the covers to be shipped nested so as to occupy butrelatively small space.

\Vith these and other objects in View, the invention consists in certain novel features of construction and combinations and arirangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view partly in section and partly in elevation illustrating my improvements in operative position. Fig. 2 is a View in longitudinal section through a series of nested covers, and Figs. 3 and 4 are perspective views of the two rings constituting the holding means of the fragile sheet which operates as a closure for the pail.

1 represents apail such as ordinarily provided for Water or fire extinguishing chemical, and which may be of any suitable material, in fact, my invention is not limited to any particular style of pail, but rather to the closure therefor. These pails are filled with water or chemical and frequently the contents are not used .for a long period.

Hence, they must be covered in order to prevent evaporation and to exclude the dirt. After the covers on such pails have stood for a considerable length of time, they become rigid, so that it is almost impossible to remove them when the contents of the pail are needed.

Specification of Letters Patent.

Patented Jan. 12, 1915. Serial No. 744,611.

It is the purpose of my improvements to provide a cover which, while preventing evaporation and excluding the dirt, can be readily ruptured at any time.

The cover comprises two rings 2 and 3 havinga sheet of material 4 clamped between them. The ring 2 is of truncated conical form, so that it maybe forcedtightly into the pail and at its upper edge is provided with an outwardly projecting flange 5, upon which the edge of the tin foil sheet 4 is clamped by the outwardly projecting flange 6 on ring 3.

These flanges 5 and 6 and the sheet 4 are preferably rigidly bound together by means of rivets 7. Ring 3 is appreciably shorter or of less depth than ring 2, and at its lower edge is provided with an internal annular flange 8 against the under face of which, the sheet 4 is held taut.

In assembling the'parts, the sheet 4 is.

placed on ring 2, and ring 3 is forced into position and secured by the rivets 7. This pressure of the ring 3 upon the ring 2 serves to hold the sheet at taut, and constitutes an air tight closure for the pail when the ring 2 is forced into the position shown in Fig. 1. As above stated, the ring 2 is of general truncated conical form which enables a plurality of such covers to be nested with the lower end of one projecting into the upperend of the other as indicated in Fig. 2. This is convenient for shipment, and furthermore, the fragile sheets 4 can better be protected in transit by this manner of assemblage.

In operation, whenever it is desired to use the contents of the pail, the user may rupture the sheet 4 by means of his hand or any tool, so that the contents of the pail can be readily poured out. When the pail is refilled, it will, of course, be necessary to use another cover or at least a new sheet of material 4 between the rings.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and tin foil or other similar alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A pail cover comprising two truncated conical rings, one ring shorter than the other and fitting snugly inside of the longenring,v

a sheet of fragile impervious material clamped at its edges 'between saidtruncated conical rings, an external annular flange on the upper edgeof each ring, and rivets projected through the flanges and securing said rings together, substantially as de- 1 scribed.

' 2. A pail cover comprising two truncated conical rings, one ring shorter than the other and fitting snugly inside of the longer ring, a sheetof fragile impervious material clamped at its edges between said truncated conical rings; 'said shorter ring having an internal annular flange against the under 'co' m of mi 'p'atent ma'y unmmea mthe cents each, Washington, DL'C."
